STARTING-CRANK v S pecification of: Letters Patent.

FOR EXPLOSION-ENGINES;

Patented ms 12, 1907.

To all whont it my concern.-

Be it known that I, ANTON Somi'rrrm, a

subject of the King of Prussia, residing at Munich, in the Kingdom of ,Bavaria, German Empire, have invented new and useful'Imrovements in Starting-Cranks for Explosivef ngines, of which the following is a complete specification. l V My invention relates to an improved starting-crank for e losive-e es, the essential feature of whic efiecting automatic release is located in the .be drawn into the groove (which can also be locate in the .handle, if.

handle of the crank.

I The invention is illustrated in the accompanying drawingi in Figure 1 is a plan of the device, and Fig. 2. a section throng the same. Y

In Fig. 1 the crank is shown in the position without load. The bolt a holds the sliding bar b by means of a catch 1)", so that the slide 6 cannot sna into the groove in the shaft.- When 'the be t a is retracted, t e slide b'will' by the Spring a desired,) the broken lines,jFig. 1, indicati this position The e 'e can nowbestarte' by turning the era overtakes the driving motion of the crank,

-' the slide b, togetherwith the connecting-rod 0 f, jointedgthereto, willfshift back, since the shaft runs in the direction of'the inclined face of the slide 11. The latter thusleaves the' groove g, and the bolt awsnap's below .the catch b ,so that the crank is released and can be taken ofl. If, however, there should be a backward motion of the engine, the crank.

starting. In this case, since the crank-hanidle is held firmly in the hand, owing to the clutch e d; \ig. 2, the connecting-rod f will raise the slide and the bolt a will sna I a move in the opposite direction to that of low the catch 6 again, so that the shaft is released, asbefore,

'Instead of the sliding bar 6 a suitable detent may be employed, and, furthermore, the catch I) might be replaced by a depression.

Having us described my invention, what Iclaim as new, and desire to secure by Let ,ters Patent ofthe United States of America,

. I In combination, a grooved shylft, a-crank mounted thereon; a spring-actuated mem-' her secured to'the crank and having an inclined end adapted to e niage in the shaftgroove; 'a spring-actuated 0 ton the crank,

adapted to engage the said spring-actuated -member; a handle for operating the crank;

the ,said member is pushed back and is
